housing by means of bolts 45. Interposed between the cap and the end of the bearing housing is a sealing gasket 46 of any suitable material. The inner surface of the cap is formed to provide a cavity with a centrally located interiorly projecting abutment 48, adapted to engage the end of the axle, and serving to take up end thrusts exerted on the axle. The upper end of the cap 44 is provided with a lubricant passageway 49, opening into the interior of the cap, and the outer end of said passageway is provided with a conventional form of lubricating fitting D, so that a suitable pressure type of lubricating apparatus may be connected to the fitting for supplying lubricant to the bearing.

Surrounding the axle I I and disposed in abutting relation to the inner surface of the inner end flange 4l of the bearing housing 40 and the Wood bearing blocks 43, is a felt washer 5|, and a metal washer 52, is interposed between the exterior of the inner end of the bearing housing'and the hub portion Illa of the adjacent pulverizer wheel l0.- By virtue of this construction the bearing proper is sealed against the entry of dust, dirt and foreign matter and in addition, serves to retain the lubricant within the bearing proper. Furthermore, the wear on the axle, the bearing, and other parts mounted on the axle is greatly reduced, and serves to prolong the life of usefulness of the implement.

Some changes may be made in the construction and arrangement of the parts of my improved implement without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.

I claim as my invention:

l. A bearing structure for a shaft comprising, a housing formed as an integral body having a chamber open at opposite ends, the inner end having an inwardly extending annular ange, a bearing liner mounted in the chamber of the housing, in registration with the flange, and a cap rigidly secured in sealing engagement with the outer end of the housing for closing the outer end of the chamber, confining the liner therein and serving to take up end thrust of the shaft,"

said cap having an annular projection on its inner face in engagement with said bearing liner and forming therewith an annular cavity surrounding the end of the shaft, and a lubricant passagewayr opening at one end to the exterior of the cap and the opposite end opening into said cavity.

2. A bearing structure for a shaft comprising, a housing formed as an integral body having a chamber open at opposite ends, the inner end having an inwardly extending annular flange, a bearing liner mounted in the chamber of the housing, in registration with the flange, a compressible sealing washer positioned intermediate the inner face of the flange and the adjacent end of the liner and adapted to surround the shaft, and a cap rigidly secured in sealing engagement with the outer end of the housing vfor closing the outer end oi the chamber, confining the liner therein and serving to take up end thrust of the shaft, said cap having an annular projection on its inner face in engagement with said bearing liner and forming therewith an annular cavity surrounding the end of the shaft, and a lubricant' passageway opening at one end to the exterior of the cap and the opposite end opening into said cavity.

3. A bearing structure for a shaft comprising a housing formed as an integral body having a chamber open at opposite ends, the inner end having a radially, inwardly extending annular flange, the inner surface of said housing being polygonal in transverse cross section, a bearing liner mounted in the chamber of the housing, the outer surface of said bearing liner being shaped to conform with the polygonal inner surface of the housing, said bearing liner being in registration with said ange and extending radially, inwardly beyond said flange, and a cap rigidly secured in sealing engagement with the outer end of the housing for closing the outer end of the chamber, said cap having a central projection on itsinner surface adapted to receive end thrust of the shaft,.said cap having an annular projection surrounding and spaced radially from said central projection and extending radially, inwardly therebeyOndQsad annular projection being in engagement with said bearing liner and forming therewith an annular cavity surrounding the end of lthe shaft.

4. A bearing structure for a shaft comprising, a housing formed as an integral body having a chamber open at opposite ends, the inner end having a radially, inwardly extending annular flange, the inner surface of said housing being polygonal in transverse cross section, a bearing liner mounted in the chamber of the housing, the outer surface of said bearing liner being shaped to conform with the polygonal inner surface of the housing, said bearing liner being in registration with said flange and extending radially, inwardly beyond said flange, a compressible sealing washer positioned between the 'inner face of the flange and the adjacent end of the liner, a cap secured to the outer end of the housing, said cap having a peripheral sealing surface, a compressible washer positioned between said peripheral sealing surface and the end of the housing, said cap having a central projection on its inner surface adapted to receive end thrust from the shaft, said cap having an annular projection on its inner surface surrounding and spaced radially from said central projection, said annular projection extending axially, inwardly beyond said central projection and said sealing surface, said annular projection being in engagement with said bearing liner and forming therewith an annular cavity surrounding the end of the shaft. and a lubricant passageway through said cap communicating with said cavity.

5. A bearing structure for a shaft comprising, a housing formed as an integral body having a chamber open at opposite ends, said housing having radially extending ears for mounting the bearing structure, the inner end having a radially, inwardly extending annular flange, the inner surface of said housing being polygonal in transverse cross section, a bearing liner mounted in the chamber of the housing, the outer surface of said bearing liner being shaped .to conform with the polygonal inner surface of the housing, said bearing liner being inV registration with said iiangev and extending radially, inwardly beyond said flange, a compressible sealing washer positioned between the inner face of the ange and the adjacent end of the liner, and a cap closing the outer end of the housing, said cap having radial ears for receiving connecting means for securing themselves to the ears on said housing and mounting the cap in place, said cap having a peripheral sealing surface, a compressible Washer positioned between said peripheral sealing surface and the end of the housing, said cap having an annular projection on its inner surface surrounding and spaced radially from said central projection, said annular projection extending axially, inwardly beyond said central projection and said sealing surface, said annular projection being in engagement with said bearing liner and forming therewith an annular cavity surrounding the end of the shaft, and a lubricant passageway through said cap communicating with said cavity.
